A cold-rolled steel sheet highly suited to press molding, the surface of said cold-rolled steel sheet having an organic-inorganic composite coating that contains an organic resin and a layered crystalline substance. Said organic-inorganic composite coating has an average thickness of 0.10 to 2.0 µm and contains, in terms of solid content, at least 0.5 weight parts of the layered crystalline substance per 100 weight parts of the organic resin. The layered crystalline substance is preferably, for example, a layered double hydroxide represented by [M2+1 −XM3+ X(OH)2][An−]x/n∠™zH2O, where M2+ represents at least one of Mg2+, Ca2+, Fe2+, Ni2+, and Zn2+; M3+ represents at least one of Al3+, Fe3+, and Cr3+; and An− represents at least one of OH−, CO3 2−, Cl−, and (SO4)2−. |
